Toxic Substances Control Act

Toxic Substances Control Act

Date: unknown
Creator: United States. Congress
Description: The Toxic Substances Control Act of 1976 provides EPA with authority to require reporting, record-keeping and testing requirements, and restrictions relating to chemical substances and/or mixtures. Certain substances are generally excluded from TSCA, including, among others, food, drugs, cosmetics and pesticides. TSCA addresses the production, importation, use, and disposal of specific chemicals including polychlorinated biphenyls (PCBs), asbestos, radon and lead-based paint.

Assessment of Knowledge on Impacts of Climate Change - Contribution to the Specification of Art. 2 of the UNFCCC: Impacts on Ecosystems, Food Production, Water and Socio-economic Systems

Assessment of Knowledge on Impacts of Climate Change - Contribution to the Specification of Art. 2 of the UNFCCC: Impacts on Ecosystems, Food Production, Water and Socio-economic Systems

Date: November 2003
Creator: Hare, William
Description: The purpose of this report is to compile and summarise the present knowledge on impacts of climate change as a basis for a consideration of what may constitute dangerous anthropogenic interference with the climate system under Article 2 of the United Nations Framework Convention on Climate Change (UNFCCC). An attempt will be made to associate projected global mean surface temperature and/or sea level changes with specific identified impacts and effects in order to assist a discussion on the operationalization of Article 2. The main emphasis will be on ecosystem effects, food production, water resources, and sustainable development.

WMO Statement on the Status of the Global Climate in 1995

WMO Statement on the Status of the Global Climate in 1995

Date: 1995
Creator: World Meteorological Organization
Description: There is continuing international concern about global warming and its potential to cause serious disruption to vulnerable social and economic sectors of society as well as to sustainable development efforts. As recently as December 1995, scientists of the World Meteorological Organization/United Nations Environment Programme (WMO/UNEP) Intergovernmental Panel on Climate Change stated that "the balance of evidence suggests a discernible human influence on global climate", through emissions of greenhouse gases. At the same time, there is a developing capability within national Meteorological and Hydrological Services (NMHSs) to provide comprehensive information on past, present, and future (seasons to a year ahead) climate and its variations, to a wide spectrum of users. The rapid development of global communications systems means that such information can be provided on a timely basis and is, therefore, of great use to national decision makers.

Federal Water Pollution Control Act

Federal Water Pollution Control Act

Date: November 27, 2002
Creator: United States. Congress. House
Description: The Clean Water Act (CWA) establishes the basic structure for regulating discharges of pollutants into the waters of the United States and regulating quality standards for surface waters. The basis of the CWA was enacted in 1948 and was called the Federal Water Pollution Control Act, but the Act was significantly reorganized and expanded in 1972. "Clean Water Act" became the Act's common name with amendments in 1977. Under the CWA, EPA has implemented pollution control programs such as setting wastewater standards for industry. We have also set water quality standards for all contaminants in surface waters. The CWA made it unlawful to discharge any pollutant from a point source into navigable waters, unless a permit was obtained. EPA's National Pollutant Discharge Elimination System (NPDES) permit program controls discharges. Point sources are discrete conveyances such as pipes or man-made ditches. Individual homes that are connected to a municipal system, use a septic system, or do not have a surface discharge do not need an NPDES permit; however, industrial, municipal, and other facilities must obtain permits if their discharges go directly to surface waters.

The Terrestrial Biosphere and Global Change: Implications for Natural and Managed Ecosystems

The Terrestrial Biosphere and Global Change: Implications for Natural and Managed Ecosystems

Date: 1997
Creator: Walker, Brian
Description: From the perspective of terrestrial ecosystems, the most important component of global change over the next three or four decades will likely be land-use/cover change. It is driven largely by the need to feed the expanding human population, expected to increase by almost one billion (109) people per decade for the next three decades at least. Much of this increase will occur in developing countries in the low-latitude regions of the world. To meet the associated food demand, crop yields will need to increase, consistently, by over 2% every year through this period. Despite advances in technology, increasing food production must lead to intensification of agriculture in areas which are already cropped, and conversion of forests and grasslands into cropping systems. Much of the latter will occur in semi-arid regions and on lands which are marginally suitable for cultivation, increasing the risk of soil erosion, accelerated water use, and further land degradation.

Integrated Land Ecosystem-Atmosphere Processes Study: Science Plan and Implementation Strategy

Integrated Land Ecosystem-Atmosphere Processes Study: Science Plan and Implementation Strategy

Date: 2005
Creator: Integrated Land Ecosystem-Atmosphere Processes Study
Description: The iLEAPS Science Plan and Implementation Strategy defines the scientific objectives and key research issues of the land-atmosphere project of the International Geosphere-Biosphere Programme. It also outlines a strategy for addressing the key research questions. The scope of iLEAPS research spans from molecular level processes - such as synthesis of volatile organic compounds in vegetation - to Earth System science issues, climate and global change. iLEAPS research emphasises the importance of connections, feedbacks and teleconnections between the numerous processes in the land-atmosphere interface. Due to the complexity and wide range of scientific issues, iLEAPS stresses the need for increased integrative approaches and collaboration, involving scientists from various disciplines, experimentalists and modellers, and international research projects and programmes.

NOAA Reports Potent Greenhouse Gas Levels Off

NOAA Reports Potent Greenhouse Gas Levels Off

Date: November 17, 2003
Creator: NOAA News Online
Description: This document provides a summary of a study by NOAA researchers and National Institute for Space Research in the Netherlands. According to the study, one of the atmosphere's most potent greenhouse gases, methane, may now have leveled off. Scientists aren't sure yet if this "leveling off" is just a temporary pause in two centuries of increase or a new state of equilibrium.
